Touchscreen Designation Point Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses face challenges in providing intuitive and error-free operation modes for users, particularly in maintaining the disposition of a designation point relative to a contact point on a display screen, which can lead to cumbersome interactions and increased chances of erroneous operations.
Innovation Solution
An information processing apparatus with a display, acquiring section, and display controller that switches between a disposition mode and a movement mode based on user interaction, allowing the designation point to be initially set and then moved in accordance with the contact point, thereby maintaining its disposition and preventing hiding by the operator's contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the designation point is moved in accordance with contact point movement, then the disposition is maintained, but the designation point may be hidden by the operator's contact
Solution Approach 1:
The patent implements two distinct operation modes that dynamically switch based on user interaction: in the first mode, the designation point maintains a fixed disposition relative to the contact point, while in the second mode, the designation point moves with the contact point to maintain visibility. This dynamic switching resolves the contradiction by adapting the system behavior to different operational contexts.
2Ease of operation
If the designation point is placed at a desired location, then operability is enhanced, but the system complexity increases due to mode switching
Solution Approach 1:
The system automatically switches between operation modes based on detected contact point movement, eliminating the need for manual mode selection by the user. The control section monitors contact point behavior and autonomously transitions between the first and second operation modes, thereby enhancing ease of operation without requiring complex user interaction with the mode switching mechanism.
3Object-generated harmful factors
If the designation point moves with contact point, then visibility is maintained, but error-free operation becomes more difficult
Solution Approach 1:
The patent provides users with the ability to switch between two operation modes: one where the designation point moves with the contact point to maintain visibility, and another where the disposition is fixed to ensure error-free operation. This dynamic configurability allows users to select the appropriate mode based on their specific operational needs, resolving the contradiction between visibility and operational accuracy.

AI summary
An information processing apparatus includes a display having a display screen that displays an image; an acquiring section that acquires information indicating a contact point which is a position where an operator is brought into contact with the display screen by a user; a display controller that makes the display screen display an image showing a designation point designated by the user; and a setting section that sets an operation mode by switching between a first operation mode in which a disposition of the designation point relative to the contact point is changeable and a second operation mode in which the designation point is moved in accordance with movement of the contact point so that the disposition changed in the first operation mode is maintained. The display controller controls display of the designation point in accordance with the operation mode set by the setting section.
